This MK3 to MK3S upgrade focuses only on the new Extruder design. Other parts of the printer can differ from yours, but there is no need to upgrade them.
Before we start disassembly, you need to print (or purchase) all the necessary parts. If you already have the parts, you can skip to the next step.
⬢For MK3 to MK3S upgrade you need to print the extruder parts, which are separated into more G-codes. Use enclosed BLACK PETG or similar material. The colour should be black to avoid issues.
⬢3D printed parts are very precise, however, there still might be a tolerance in the printed part and same goes for the size of the nut.
⬢Therefore it might happen, that the nut won't fit easily in or might be falling out. Let's see, how to fix it:
⬢Nut won't fit in: use a screw with a thread along its entire length (typically: M3x10, M3x18) and screw it from the opposite side of the opening. While tightening the screw, the nut will be pulled in. Remove the screw afterwards.
⬢Nut keeps falling out: Use a piece of tape to fix the nut temporarily in place, as soon as you insert the screw in, you can remove the tape. Using glue isn't recommended as it can partly reach into the thread and you won't be able to tighten the screw properly.
⬢Every time we recommend to use the "screw pulling technique", you will be reminded with Joe's avatar ;)
To successfully finish the assembly please follow all these:
⬢Always read all the instructions at current step first, it will help you to understand, what you need to do.
⬢Don't follow pictures only! It is not enough, the written instructions are as brief as they could be. Read them.
⬢Read the comments from the other users, they are great source of ideas. We read them too and based on your feedback improve the manual and the entire assembly.
⬢Use a reasonable force, the printed parts are tough, but not unbreakable. If it doesn't fit, check your approach twice.
⬢Most important: Enjoy the build, have fun. Cooperate with your kids, friends or wives. However, we take no responsibility for possible fights ;)
